The 30-year-old actress was just 11 years old when she had to get plant an innocent kiss on the hunky actor in 1994 movie 'Interview with the Vampire', but she remembers being less-than-impressed with her heartthrob co-star.

She told Bullett magazine: ''It was just a peck.

''I remember Brad would watch lots of 'Real World' episodes. He had this long hair. He was just a hippie-ish cool dude.

''Everyone at the time was like, 'You're so lucky you kissed Brad Pitt,' but I thought it was disgusting. I didn't kiss anyone else until I was 16, I think. I was a late bloomer.''

In 2008, Kirsten - who is in a relationship with Garret Hedlund - checked into rehab to be treated for depression and she says her subsequent self-examination taught her to change her priorities in her life.

She explained: ''I just needed a break to grow into myself. I'd been working since I was a kid in a very people-pleasing environment. It changed my whole perspective about what I do and how I do it.

''I used to be someone who worked a lot, and now I'm in one movie a year.''
